Overview
The IC694CHS398 connects to the main rack through a high-speed serial expansion interface. Therefore, it enables reliable data exchange across local and expansion racks with minimal latency. In addition, the backplane supports a wide range of RX3i and compatible I/O modules. Its rugged industrial design ensures consistent performance in demanding factory conditions.
